LINE-GUIDE FOR COPYISTS.

Specification of Letters Patent.

Patented Sept. 23, 1 913.

Application filed January 4, 1913. Serial No. 740,143.

To all whom it may concern:

Be 1t known that I, WILLIAM C. SenoonN, a citizen of the United States, and a res1- dent of Colville, in the county of Stevens and exact description. My mventlon relates to l1ne grades for use by copyists and in which a line-guide arm is adjustable longitudinally for line spacing.

The device comprises a supporting frame having claniping means adapted to engage a book or the like, for holding the supporting frame in position, and a second frame mounted on the supporting frame and carrying adj ustably, a lateral line-guide arm.

The improved construction is designed to increase the e'ilieieney of devices of the general character indicated, as well as economy of manufacture, simplicity of adjustment and control, and also provides for the ready disn'iembering of the device for bringing it into compact form for shipping or stowage.

The distinguishing features of the invention and the important structural elements characterizing the preferred embodiment which is illustrated as an example will be more particularly explained in the specilie description hereinafter to be given.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front view of a line guide embodying my invention; Fig. 2 is an end view; Fig. 3 is a transverse section;l. ig. t is a detail sectional plan View of the slide, the view including a portion of the line-guide arm and fragments of the guide frame therefor; Fig. 5 is a side view of the slide carrying the lineguide arm, the said arm being shown in end view; and Fig. (3 is a bottom plan view of the slide, and a portion of the line-guide arm.

In constructing the illustrated embodiment of my invention, a supporting frame 10 is provided, in the form of an elongated bar, which at a point about centrally thereof is equipped with a clamp 11, hereinafter more particularly referred to, adapted to hold the supporting f time to a book A, or other support, the said frame 10 having at the ends thereof, posts 12. The posts 12 are adapted to removably receive the transverse end members 13 of a guide frame which is provided with parallel longitudinal guide rods 14:, 15, and preferably said end members 13 are extended laterally at one side, to provide bearing arms 16 adapted to bear upon the surface of the book A.

A lateral line-guide arm 17 is fitted with means for giving it adjustable longitudinal movement on the guide rods 14, 15, for which purpose a slide box 18 is provided, carrying the said line-guide arm. The slide box has registering holes 19 in opposite sides thereof through which the guide rods 14:, 15 extend. If desired, the line-guide arm 17 may have an extension slide 20, movably held thereon to vary the total length of said arm.

The clamp 11 in the form shown has a bottom plate 21. rigid with the supporting frame 10, and constituting at its forward end a clamp jaw, the rear end 22 of which constitutes a handle or gripping member, and above said plate 21 a movable clamp jaw 23 is mounted, the rear end 2t of which constitutes a handle or grip, and a bowed plate spring 25 interposed between the handles 22 and 2t and secured to both, normally tends to close the jaw 21, 23.

The posts 12 have shoulders 26 thereon between the upper and lower ends, at a height to sustain the end members 13 of the guide frame above the clamp 11, so that in the longitudinal movements of the slide box 18, said box will clear the clamp.

To adjustably engage the slide box 18 with the guide frame, one of the guide rods, as 15, is formed with teeth 27, and a dog 28 engages said teeth for line spacing. The dog has connection with a finger lever 29 fulerunual on a post 30 on a side of the box 18, one end of the lever engaging the outer end of the said dog, and the dog is slotted as at 31, to embrace the guide rod l t in moving into and out of engagement with the other guide rod 15. A. spring 32 is secured at one end. to a partition 33 in the box 18, the free end of the spring being received in an orifice in the dog 28; t1 2 arrangement is such that the spring 32 normally tends to maintain the dog in engagement with a teeth 27, but may be readily released by pressure of the finger on the lever 29 for sliding the box 18 longitudinally of the guide rod for spacing the line-guide arm 17.

To removably secure the line-guide arm 17 to tli e slide box said arm, as seen best in Fig. 6, is formed with a longitudinal slot 34C at its inner end, which slot receives threaded studs 35 on the under side of the box, the connection being completed by suitable nuts 36; thus the line-guide arm may be removed and disposed parallel with the supporting and guide frames, whereby the device may be packed into small compass for shipment and when not being used.

The described construction affords a practical means for carrying my invention into effect, and I would state in conclusion that I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the lnvention.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. A line guide, comprising an elongated supporting frame having a clamp between its ends for securing it in place on a book or other support, and posts extending upwardly near the ends of the said frame, a second frame removably engaging the said posts and ranging longitudinally above the clamp, and a lateral guide arm having sliding connection with the said second frame for movement longitudinally of the latter.

2. A line guide, comprising a supporting frame having end posts rising therefrom, the posts being provided with shoulders thereon at points between the upper and lower ends of the posts, a clamp on the supporting frame between said posts and below the plane of the mentioned shoulders, a second frame having end members removably fitting the posts of the supporting frame and resting on the shoulders of the posts, and a slide on the second frame, said slide having a lateral line-guide arm.

3. A line guide, comprising asupporting frame having end posts rising therefrom, the posts being provided with shoulders thereon at points between the upper and lower ends of the posts, a clamp on the supporting frame between said posts and below the level of the mentioned shoulders, a second frame having end members removably fitting the posts of the supporting frame and resting on the shoulders of the posts, said second frame having bearing arms near the ends projecting laterally to bear on the surface of the book or other support, and a slide movable on the said second frame between the end members and bearing arms thereof, said slide having a lateral line-guide arm.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
